The single-width 3U-sized P635 PXI frequency counter offers eight channels to monitor 0.06-Hz to 100-kHz pulse sources. The board provides TTL as well as differential inputs ranging from ±20 mV to ±20 ...
In my previous design idea, a design for a simple GPS disciplined oscillator (GPSDO) 10 MHz reference was presented. A note at the end of that article describes the realization that a frequency ...
Making a microcontroller perform as a frequency counter is a relatively straightforward task involving the measurement of the time period during which a number of pulses are counted. The maximum ...
The prescaler described here connects to the front end of a 100-MHz frequency counter to extend its coverage range to 10 GHz. The circuit is a far less expensive way to measure frequencies above 100 ...
The author is a broadcast contract engineer who has a unique way of measuring the carrier frequency of the AM stations in his care. Making off-air frequency measurements of AM broadcast stations can ...
Like many people who repair stuff, [Learn Electronics Repair] has an oscilloscope. But after using it to test a motherboard crystal oscillator, he started thinking about how people who don’t own a ...
